Brief summary
Despite the massive use of intracranial pressure in neuro-resuscitation, there is still no cerebral compliance evaluation index used in current practice to guide therapy. In treatment guidelines for intracranial hypertension, patients are placed in a prone position at about 30 degrees. Several times a day, during nursing care, patients are flattened, which corresponds to a cerebral compliance test by adding a volume of cerebrospinal fluid to the cranial box.
Detailed description
This study aims to analyse the shape of the different components of the intracranial pressure waves (P1, P2, and P3) when the patient is flattened to determine an index to define the level of cerebral compliance.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Intracranial pressure (mmHg) | Year : 1 | Intracranial pressure is measured before (Raising the head by 30°) and during the flattening (Raising the head by 0°). Theses measures are done twice a day. The mean of theses values is calculated. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Correlation between ICP (Intra Cranial Pressure) doses and cerebral compliance | Year : 1 | Compare the ICP (Intra Cranial Pressure) dose value with the compliance index during the period before or after the flattening |
